Gas Monkey Ferrari F6 — The World's First 6x6 Testarossa, With 1,200 HP

What Is the Gas Monkey Ferrari F6?

The F6 started life as a damaged Ferrari Testarossa — one of several ex-movie cars from the film Infinite that Richard Rawlings bought. Rather than restore it, Gas Monkey Garage stretched the chassis by roughly three feet, added a third axle and turned it into a one-of-one six-wheeler. It is, by the team's own description, the most ambitious project in Gas Monkey history.

Technically it is a 6x4 — six wheels, with power going only to the four rear wheels across two rear axles — but the “6x6” nickname has stuck thanks to its military-grade, science-fiction stance.

1,200 HP From a Corvette V8

The original Ferrari flat-12 is gone. In its place sits a supercharged 6.2-litre LT4 V8 — the engine from the C7 Chevrolet Corvette Z06 — built up by KTech and tuned to produce roughly 1,200 hp, about ten times what the standard Testarossa made when new. Power runs through a driveline that mixes General Motors and Audi components, which Gas Monkey says actually makes the car easier to maintain than a stock Ferrari.

The rearmost section uses a fully independent rear suspension and beefed-up Wilwood brakes to cope with the extra mass and the doubled rear footprint.

F40 Styling and $60,000 Wheels

The body has been completely reworked but stays surprisingly faithful to the Testarossa, keeping its signature side strakes and slatted engine cover. The front end borrows fixed headlights and aggressive intakes from the F40 playbook, while the rear gains a huge chassis-mounted wing for downforce. The interior follows the F40 theme too: stripped out, with a three-spoke Momo steering wheel, exposed shifter, digital cluster and carbon-backed Recaro buckets.

The headline detail is the rolling stock — a set of fully bespoke wheels designed specifically for the F6 that reportedly cost about $60,000 to manufacture, more than many new cars cost outright.

A Build Full of Drama

The road to the reveal was messy. Gas Monkey Garage initially worked with Danton Art Kustoms and Frechy Export LLC, after buying a six-wheeled Humvee from them that later sold at Barrett-Jackson for $750,000. That sale was meant to fund the Ferrari project, but the partnership collapsed amid public accusations over money and credit. Rawlings says the car arrived needing extensive rework — fabrication, paint and panel fit all had to be redone — before he and partner John Clay Wolfe finished it themselves.

$1.5 Million — and a Letter From Maranello?

The finished F6 made its public debut on May 23, 2026, with track footage, and carries a $1.5 million sticker. Ferrari has historically been protective of its brand and has gone after unauthorized modifications before, so a one-off this loud is bound to spark debate among purists. Love it or loathe it, the F6 is exactly the kind of audacious, rule-breaking machine that gets the whole car world talking — a reminder that the wildest builds often come from a garage, not a factory.
